A recent investigation reveals that women’s running shoes may be limiting their athletic potential.
Published in BMJ Open Sports & Exercise Medicine, the research indicates a “significant gap in running shoe design” that overlooks women’s anatomical differences.
“Most so-called women’s running shoes are not genuinely designed for women,” asserts the study’s lead author, Dr. Chris Napier, an Assistant Professor of Biomedical Physiology and Kinesiology at Simon Fraser University in British Columbia, Canada, as noted in BBC Science Focus.
“We typically base our models on men’s feet, merely scaling them down and changing the color, a method often described as the ‘shrink and pink’ approach.”
However, Napier emphasized that this method does not “account for the real anatomical distinctions between male and female feet or the way women run.”
Consequently, women’s running shoes may not fit well, potentially hampering performance.
In this study, researchers gathered 21 women to discuss their preferences for running shoes and how their needs might evolve over their lifetimes.
The participants ranged in age from 20 to 70 and had between 6 and 58 years of running experience. Eleven individuals ran recreationally, averaging 30 km (19 miles) weekly, while 10 were competitive runners, averaging 45 km (28 miles) weekly.
Most women expressed a desire for shoes with a broader toe box, a narrower heel, and additional cushioning. Napier noted that this aligns with the general differences in foot shape between men and women.
“Women have distinct lower extremity anatomy, such as wider pelvises and shorter legs relative to body size. This influences running mechanics and the forces exerted on the legs,” says Napier.
Among the participants, mothers reported needing larger shoe sizes, wider fits, and more cushioning and support during and post-pregnancy.
This study is small and qualitative; participants were recruited via posters in stores in Vancouver, Canada, meaning findings may not be universally applicable.
Still, Napier hopes that the research will resonate with female runners.
“During our focus groups, many participants experienced an ‘aha’ moment when they realized their shoe issues were not isolated but a common experience among female runners,” he stated.
Napier also expressed hope that the study acts as a “wake-up call” for the footwear industry.
Footwear manufacturers have invested billions in developing running shoes that prevent injuries, enhance comfort, and improve performance.
Most running shoes are molded to a foot-shaped template based on male anatomy, which is then used across their products.
As a result, “a significant portion of the running community is essentially using shoes that are not intended for them,” Napier explained.
